Hi. New user here, long time lurker, this topic encouraged me to sign up.
I really like this collaborative games creation idea. One idea I'd like to add to your concept is a tutorial section, as I'm sure there are plenty of Amiga fans and users that would like to help with programming, art, etc... but don't have the necessary knowledge. Once tutorials were written on the subjects teams could assemble themselves to create simple freeware games that made use of their new knowledge. As the competence of these teams grew, the volume of quality Amiga games would increase (and hopefully the amount of new tutorials also). What do you think?
Also, I'd like to know whether support of certain platforms would be encouraged, or will it be a free for all? I mean clearly games can and should be made for all Amiga platforms, but I would say to get the most benefit, support should be for OS 3.9/4 and AROS. All IMO of course.
